14 claims. (C1. 1419 v 'I'his invention relates to an improved washing machineof the type shown in my Reissue Patent No. 17,984, issued March 3rd, 1931. Washing machines of this type generally comprise a substantially enclosed container adapted to be partially lled with a cleansing liquid such as a detergent laden water, into which dishes, clothes or other articles to be cleansed are placed. The cleansing fluid is agitated by creating a partial l0 vacuum over the surface thereof, and this is usually accomplished by drawing air from thev it escapes upwardly through the water, thereby surging, swishing and otherwise agitatng the washing liquid.

The general object of the present invention is to provide an improved, compact, portable washing machine, operable in accordance with the principle of operation of the device shown in my former patent, but wherein the washed articles may be efiiciently rinsed and quickly dried. .V

A further object is to provide a dish-washing machine, adaptable for domestic use, with suitable drain and water connections, which may be readily adjusted for drains and water taps of various heights and relative positions, and to provide such machine with means to raise the water from the container and discharge it into the drain, even though the latter be at a higher elevation than the machine.

Another object is to provide a washing machine which will normally retain sufiicient water to maintain the contents thereof moist when not in operation, thereby preventing the encrustation of dirt on articles placed therein, which are to be washed in the future:

A further object is to provide an improved structure for supporting articles to be washed in the path of greatest agitation of the washing uid.

Other objects of the invention will become apparent from the following description and claims considered together with the accompanying drawings, which illustrate my invention, as applied to a machine for Washing dishes.

The washing machine, as shown in the drawings, comprises a casing 10 within which dishes or articles rmay be washed, rinsed and dried. 'I'he casing 10 is mounted on a suitable base or frame 11, which is supported by legs 12 and provided with suitable casters 14, to permit the machine to be readily moved from place to place, (see Fig. 12). The casing 10 is provided with an improved means for agitating the water and for the circulating of currents and air therethrough in an advantageous manner. Said means may comprise in general a motor 15 (see Figs. 5 and 6), adapted to rotate a suction fan 16, to draw air and vapor from the top of the casing and force it through suitable conduits towards the bottom of the casing, where the air is permitted to escape upwardly through an annular dish supporting compartment and cause surging'and gurgitation of the cleaning fluid in a rapid'manner. The casing is also provided with spray conduits 13, adapted to communicate with a water tap 17 to facilitate the rinsing of the washed articles. A suitable pump mechanism 18 is located in the lower portion of the casing and is adapted to be connected to the motor 15 by a suitable 'clutch mechanism 19, controlled by a lever 20, which extends outwardly from the frame 11. The pump 18 communicates with an outlet conduit 21, adapted to discharge the liquid from the machine into a suitable drain, as' indicated at 22. 'I'he casing is provided with a suitable cover 25, which engages the upper edge 26 of the casing 10, making a lsubstantially air-tight connection therewith. i

The casing 10 of my improved washing machine comprises a cylinder 30, the lower end of which is curved inwardly and downwardly, form .ing a. sloping bottom portion 31, which terminates in an inwardlyextending annular flange 32, to which a closure member 33 and the base 11 are secured by suitable bolts 34. The upper edge of the cylinder 30 terminates in an outwardly extending bead 35, which carries a protecting member 36, preferably made of rubber or some similar material, and which c oacts with a suitable cover 25.

In Fig. 1, I have shown two forms of covers, either of which may serve to seal the washing compartment when the device is in operation, a

preferred form 25 being illustrated in full lines, and a modified form, 25a being illustrated in dotted. lines. The cover 25 comprises a substantially at plate of glass or wood or any lightweight water-proof composition material, and carries a bead 37 at its periphery. The bead 37 is adapted to abut the upper and inner surfaces of the bead 35 of the casing, the rubber sealing member 36 forming an air-tight seal therebetween. The cover 25a comprises a metallic plate 38 having an annular trough 39 adapted to receive the sealing member 36. The latter cover is maintained in place on the casing by-atmospheric pressure on its top surface, when the pressure within the container is reduced below that of atmospheric pressure, as will hereinafter be described. The cover 25, however, does not depend entirely upon this difference in pressures to retain it in position on the cylinder 30, but is retained by a tight-fitting, downwardly extending annular iiange 40, which projects into the casing and contacts with the inner surface of the sealing member 36.

The base 1l, which supports the casing 10, comprises a pressed metal cylindrical drum 43, having an inwardly extending top ange secured to the casing 10 by bolts 34', as heretofore described. The base 11 is slightly smaller in diameter than the casing and its upper face is sloped to substantially conform to the slope of the bottom 31 of the casing. Adjacent its periphery the upper face of the base 11 is provided with an annular groove 45 adapted to receive a resilient supporting member, such as the rubber tube 46 which supports the casing 10 adjacent its periphery. The flange 32 of the casing, to which the base is secured, is also gripped between gaskets 47, preferably rubber. Therefore noise andvibration set up within the casing is insulated from the base 11 and partially absorbed by the gasket members. The supporting legs 12 are secured to the base 11 by welding, riveting or any other suitable manner, and `are of such length as to bring the upper end of the casing l0 to a height convenient for the operator to place and remove articles to and from the casing.

The motor 15 drives the fan 16 to create a partial vacuum at the surface of the liquid within the container. The motor 15 is preferably axially located relative to and Within the casing 10 above the normal water level thereof. Themotor is best illustrated in Figs. 5 and 6, and comprises an armature 50, and field members 51, all contained within a housing 52, the upper end of which is secured to a dome shaped cap 53, in turn secured by suitable bolts 54 to an outwardly extending annular flange 55 of a cylinder 56. The lower end of the cylinder 56 is'open, and is secured or Welded to an upwardly extending annular flange 57 of the bottom closure member 33 of the casing 10.

The air pressure in the upper portion 30a of the easing 30 is decreased by the fan 16, thereby creating a partial vacuum in the container 30 above the water line thereof. The fan 16 is rigidly secured to the upper end of an armature shaft 58 of the motor 15. This shaft extends through a boss 59 in the housing 52, and through an opening 60 in the cap 53. Suitable packing 62, retained within the boss 59 by the cap 53, prevents the liquid contained within the casing from entering the motor housing. The fan 16 comprises a dished plate 63 having a hub portion 64, rigidly secured to the armature shaft 58. The plate 63 is provided with a series of upstanding fan blades 65, 'which extend from the hub towards the periphery of the plate, and have a reduced area'66 adjacent the hub, so that they will draw the air from the portion 30a of the casing through an opening 67 in a housing 68, which extends around and is spaced apart from the cylinder 56, forming a passageway 69 therebetween. The lower end of the housing 68 is conical, aring outwardly as indicated at 70, and extends to within a comparatively short distance from the bottom wall 31 of the casing 30.

To permit the housing to be readily. removed for cleaning the various passageways, the housing 68 is removably supported on brackets 71. rIhe upper ends of the brackets 71 are secured to a cylinder 72, which liesA intermediate the housing 68 and cylinder 56 and which is secured at its upper end to the motor housing 52, by bolts 54 heretofore described. The lower ends of the brackets 71 are secured directly to the cylinder 56. Each bracket 71 has a leaf spring 73 secured to its inner face, the upper or deformed ends of which pass through openings 74 in the bracketsV 71, and engage suitable recesses 75 in the housing 68, thereby securing the hous-A ing 68 to the bracket. This permits the removal of the housing 68 and at the same time it prevents rotation of the housing during the agitation of the cleansingviluid. The cylindrical and conical portions of the housing 68 are joined by an annular horizontal flange 76, which rests upon a rubber or fabric ring 77, carried by outwardly extending ears 78 of the brackets 71, thereby limiting the downward movement of the housing and permanently controlling the distance between the lower edge 79 of the housing and the bottom wall 31 of the casing 30.

The conduit 69' through which the air passes from the top to the bottom of the housing 30, also communicates with the atmosphere. It will be noted, as shown in Fig. 6, that the cylinder 56 is spaced apartfrom the motor housing 52, leaving a passageway 80 therebetween. The motor housing 52 is extended downwardly by an annular band 81, adapted to carry a tube 82 cf fibrous or other sound-absorbing material, which extends to the lowermost edge of the container 30. Both the band 81 and tube 82 are separated from the casing 56, thereby extending the passageway 80 downwardly to an opening 83 in the closure member 33, which forms the bottom cf the housing 30.

The agitating action of the liquid within the housing 30 is so turbulent that I find it desirable to provide protecting means for the opening 67 in the'housing 68, which communicates with the fan 16. To this end I provide a dished platelike member 170, which is spaced apart from the upper surface of the housing 68 by spacing members 172, and is secured thereto by suitable bolts 171. It will be noted that the cross-sectional area between this cap v1'10 and the top of theI housing 68 is such lthat the area between the two members increases as it reaches the center, thereby preventing any restricting action by the cover or cap 170.

To prevent the articles that are to be washed from dropping beneath the conical portion 'l0 of the housing 68, I provide a supportingfrack 90. In the drawings, I show the rack 90 constructed to support dishes. In the drawings, the rack is best illustrated in Figs. 3, 4 and 5, and comprises a plurality of radially extending L- shaped supporting wires 91, onel leg of each of which rests upon an outwardly extending flange 92 of the conical portion 70 of the housing 68,

while the other end of each wire 91 rests upcn Y the bottom 31 of the casing 30 adjacent its periphery, as indicated at 93. These radial wires are connected by suitable continuous annular wires or bands 94, which are preferably welded to the radial wires. To prevent breakage and marring of 'the articles to be washed, I find it preferable to coat the wires 91 and 94 with rubber, as indicated at 95. As shown', the wire rack 90 is formed and then coated with rubber, thereby filling the crevices between the wires 91 and 94, and lpreventing the accumulation of dirt therein. 'Ihe lower edge of the cone 70 is likewise covered with a rubber protecting ring k96, which prevents breakage of the article to be washed. It will be noted that the ends of the supporting members 91 of the rack 90 are coated with rubber, to prevent metal to metal contact between the legs and the casing 30, and thereby greatly reducing noise of operation.

The washing action of the machine is as follows: The machine is ilrst filled to the line marked L (Fig. 1) with a washing liquid, such as a soapy, hot water. The articles to b e washed, such as the dishes D, (Fig. 1) are then placed on the rack 90. It will be noted thatit is not necessary that the articles be entirely covered with the liquidfas the washing is caused by the agitation of the liquid, and it is found that withl the apparatus provided the liquid is carried to the very top of the containerf30. After the dishes have been placed within the casing 30, the cover 25 is set in place and the motor energized by a suitable switch. The fan 16 then reduces the air pressure in the upper portion of the casing 30 by drawing the air therefrom and forcing it down through the passageway 69. Atmospheric 'pressure then acting through the conduit 83 and openings 98 in the upper end oi' the housing 56, downwardly through the passageway 69, acts upon the surface of the water within the housing 68 and cone 70. Due to the decrease in air pressure at the top of the water in the container 30, andthe atmospheric pres-y sure which acts upon the water within the housing 68, the water within the housing 68 and the cone "70 is forced down and out into the space 30h between the housing 68 and the container 30, thereby raising the level of the water in the portion 30h of theY container. When the pres- -sure in the upper portion 30a of the container 30 is so reduced that practically all the water within the housing 68 and cone 'l0 has been drawn or forced by atmospheric pressure into the housingv 30, air will escape from beneath the cone 'l0 into the housing 30a, and through the water within the casing 30 to balance the pressui-es. This action is practically instantaneous,

,hence greatly agitates the water and causes it to be swished about the entire area between the casingv 30 and the housing 68. Likewise, because l of the quantity of air being drawn into the container 30 being so great, and is accomplished practically instantaneously, the'pressure within fthe container is almost immediately brought to atmospheric pressure, at which time the water within the container quicklyrecedes, again filling the cone 70 and further agitating the liquid. The fan 16, which rotates continuously, again beglns to decrease the pressure above the surface of the water in the container 30. This agitating of the liquid within the container 30 is therefore intermittent and' causes the watery to bel swished from side to side and spurted intermittently upwards, throughout vthe casing 30, asv

that the drain on the ordinary kitchen sink may be used, regardless of its elevation and without raising the machine to such a height that the draining could be accomplished by gravitation, which, in many instances, would render it incon- -venient for the operator to place and remove arl yticlesxtoand from the machine.

TheI pump 18, which draws the water from the `casing 10, is located at the lowermost portion of the casing and is preferably of the centrifugal type. 'I'he pump 18 comprises a pump rotor 100 1I0 mounted in a housing 101, which is secured to the lower closure member 33 of the casing 30 by suitable bolts -(not shown). The closure member 33 is provided with a pair of openings 103, which are joined by a suitable manifold 104 disposed be- 115 tween the casing 30 and the pump housing 101 and integral with the latter. The pump rotor 100 is rigidy secured and supported by a vertically extended shaft 105, axially located relative to the armature shaft 58. The shaft 105 is supported 120 in suitable bushings 106 and 107, carried in a vertically extending sleeve 108. Secured to the upper en d of the shaft is one member 109 of the clutch mechanism19. 'I'he clutch member 109 is the male member of the cone clutch 19 and car- 125 ries on its conicall face suitablefriction means 110 rigidly held to the clutch member by suitable bolts 111. The clutch member 109 is adapted to coact with a femae cone 112 rigidly secured to the lower end of the armature shaft 58. The

clutch members 109 and 111 are normally held in a disengaged DOSition by a spring 115 carried within the housing 108, and acting upon a shoulder 118 of an enlarged portion 117 of the shaft 105, and which normally urges the shaft to its 13% lowermost position. Thedownward movement of the shaft is limited by a shoulder 118 Jon the shaft, which coacts with the uppermost end of the bushing 106.

When it is desired to drain the casing 30, the

clutch control mechanism 20 (illustrated in Figs. 2 and 6) is operated to raise the shaft 105, and cause the clutch member 109 to engage the clutch member 110, thereby rotating the pump rotor 100 and causing the waterwithin thecasing 30 to 145 be drawn through the conduit 104 into the pump housing and discharged through an outlet port1 114 (Fig. 1) which port is connected to a tube 116a, which extends substantially horizontally to 8 Point beyond the periphery of the casing 30. 15.0

and then upwardly as at 11'1a, and issecured,to the casing by suitable supporting members 119 and 120.

The vertical portion 117a of the tube 116a is so arranged as to leadl the liquid into the drain 22. Telescopically arranged within the tube 116a is a second tube 121, which has a horizontally extending portion 122 adjacent the uppermost end, terminating in a downwardly extending spout 123, adapted to be positioned over the drain. The telescopic tubes are so arranged that the tube 121 may be moved up or doWn,-or may be rotated reative to the tube ll'la to place the outlet 123 in communication with the drain 22. Suitable packing 124 is retained in position on the tube 116 by a packing nut 125, providing a water-tight seal between the two telescopic tubes. It will be noted that the vhorizontal portion 122 of the tube 121 is curved, as is best illustrated in Fig. 3, and this curvature conforms substantially to'the curvature of the casing 30, so that when the machine is not in use, the tube 121 may be swung about the tube 116a to a position where the horizontal portion 122 lies close to the casing 10, rthereby providing a compact arrangement.

The clutch 19, heretofore described, is operated by a suitable lever and cam mechanism 20, best illustrated in Figs. 2, 5 and 6. The lowermost end of the shaft 105, which carries the clutch member 109, is rounded as at 130, and is adapted to be raised and lowered by a plunger 131, which coacts with the periphery of a suitable eccentric disc or cam 132, rigidly secured to a shaft 133, which is mounted in a housing 134, forming the lower closure member for the pump housing 101. The shaft 133 extends to the exterior of the housing 134 and carries at its outer end a lever 135, to which is pivotally connected as at 136 an operating rod 137, which' passes outwardly through a bushing 138 at the base member 11. The operating rod 13'7 is provided 'at its outermost end with a suitable knob 139, permitting it to be readily withdrawn to rotate the shaft 133, causlng the raising of the plunger 131 by the eccentric disc 132. This carries the clutch member 109 'into contact with the clutch member 110, thereby causing the pump rotor to be rotated and to drain the casing 10.

After the wash water has been drained from the casing 10, the articles are rinsed with hot water, which operation is readily accomplished by operation of the household hot water spigot which has been connected to a suitable conduit communicating with the interior of the housing 10. Secured to the side of the casing 30 by the securing members 119 and 120, heretofore described, is. a second telescopic tube arrangement 140. The upper end of this tube has a substantially horizontally extending portion 141, to which is secured a coupling device 142, adapted to couple the tube 140 to a water tap, indicated at 17 (Fig. 11). The coupling device 142 comprises a body porti-'M` 143, adapted to receive a rubber gasket 144, which is secured in place in an opening in the upper portion of the body by a suitable retaining ring 145. The inner surface of the gasket 144 is conical, as indicated at 146, so that it may be wedged tightly in place on the water tap. The tube 140 is constructed in the same manner as the tube 1163, -1171 heretofore described, and is adapted to be swung from side to side kor moved up and down, as desired by the operator. Thehorizontally extending portion 141 of the tube 140 is curved, as indicated at 1'46, on Fig. 3, and is adapted to be swung to a position adjacent the container 30 when the machine is not in use. The lower end of the tube 140 is connected by a horizontal tube 148 to a manifold 149, which passes through the closure plate 33, and is connected to a manifold 151, located within the casing 30 below the conical housing '10.v The manifold 151 is supported as shown in Fig. 6 by a plurality of supporting members `152, which are secured in position to the closure plate 33 by the bolts 34. The manifold 151 has connected to it a plurality of tubes 155 and 156, which extend radially between the lower portion of the conical housing '70 and the bottom 31 of the casing 30. The'tubes 155 and 156 are protected with a rubber coating 157, and have secured at their outermost ends nozzle members 158 and 159, respectively. The tubes 155 extend a short distance beyond the lower edge of the housing 70 and the stream of wate'r from the tap is directed from these tubes upwardly into the casing 30 from openings 160 in the nozzles 158. The tube 159, however, extends outwardly and upwardly following the contour of the housing 30, to a point a short distance below the top of the cas-l ing 10, and are provided at their upper ends with nozzles 159 having openings 161 adapted to direct the spray of water upwardly against the top 25 of the casing, where the water will be deflected downwardly, thereby thoroughly rinsing the articles within the container.

I prefer to bend the uppermost ends 162 of the tube 156 inwardly away from the Wall of the casing 30, so that they may be used to wash articles. In Fig. l, I have shown these tubes as supporting cups C. It will be noted that the articles C will lie above the water line L of the container. no This, however, is immaterial, as the agitating action of the liquid heretofore described is so turbulent that it carries the liquid up to the cover and is of adequate force to thoroughly wash the articles, even though they be situated above the norun mal water line. If desired, the motor 15 may be operated throughout the rinsing operation, thereby providing a thorough agitation of the water within the housing and further increasing the effectiveness of the machine during the rinsing op- 1m eration.

After the articles are rinsed, they may be dried in the machine. This is accomplished by the draining of the rinse Water, by means of the pump mechanism 18, the operation being similar in all 1 respects as the operation for the draining of the wash water. The cover 25 is then removed and the motor 50 set in operation. This will-cause air to be drawn from without the container and forced through the passageway within the housu ing 68 and the cone 70, down to the bottom of theY ring, and then up through the portion 30a and 30h in the container 30, thereby effectively drying the articles within the container.

It is sometimes desired to use a Washing ma.- 13s chine for storing articles, to be washed in the future. Hence, I have provided means to prevent dirt and other accumulation on such articles from becoming encrusted. The pump mechanism 18 is situated at the base of the container' 10, and the pump, being a centrifugal pump, will never entirely exhaust the rinse water from the outlet tube 116, when the clutch 19 is operated to disconnect the pump 18 from the motor, and the liquid in the outlet tube 1,116 will flow back, filling the pump chamber and the conduit 103. Hence,rif the articles are stored Within the container 30, and the cover placed in position, the air within the container will remain moist at all times, thereby preventing dirt and other accumu- 1Z0 and bottom portions thereof, said conduit spaced' Iatons from drying on the articles to be washed. It -will be noted that I include a novel means of cooling the motor 15. In Washing machines heretofore made, the motor 15 has been situated entirely outside of the machine, partially due to the fact that it is dilcult to cool the motor and at the same time prevent moisture from accumulating therein and damaging the parts. It will be noted that I provide the motor 15 with a fan '180, which is rigidly secured to the armature shaft 58v adjacent the upper end and .within the casing 52. A passageway 181 between the f elt ring 82 and the sleeve 108 then communicates with the motorhousing 52 by means of openings.182 in 'the lower end thereof. Air is therefore drawn from the atmosphere through the passageways 181 and 182 into the motor housing by the fan 180. 'Ihis creates a pressure inthe upper end of the motor housing, which pressure acts through the passageway 83 downwardly either through the open ings 98 into the housing 68 and 70, or downwardly through the passageway 83, returning to atmosphere, depending upon the pressures within the passageway 83 and 69.

From the foregoing description, it will be seen y.that'I have provided a washing machine for cleansing dishes or other articles which will thoroughly wash, rinse and dry such articles, and which washing'machine includes an improved means for eiciently agitating the water by the circulation of currents of air through same. Likewise, I have located the motor, which operates the fan to cause the differences in pres' sure within the container, in a most advantageous position, wherein the passageways are as short as possible and located conveniently to thepoints of intake and outlet. It will also be noted that I have provided a washing machine, the top of which is located at a height convenient for the operator to place and remove dishes or other articles to and from the container, and which machine is provided with a pump mechanism adapted to draw the waterfrom the machine and force it into a drain, even though the machine lie in a plane below that of the drain opening. It will also be apparent that I have provided means for connecting the machine with a water spigot and a drain which connecting means is readily applied to drains and spigcts of various heights, and in various relative vertical and horizontal positions, and which connecting mechanism may be readily positioned adjacent the con# tainer when not in use, thereby providing a compact arrangement. I also provide a suitable supporting base, to enable the movement of the machine from Iplace to` place, as desired by the operator.
